Bret wanted a 2" hole in solid rock, I was telling him how I do it with a small genset and the biggest hammer drill made, and up to 2" x 2' overgrown masonry bits. Most of my fence line is exposed, solid rock, no dirt at all and sometimes not even any scree on the surface. The rest is calichi which will turn tee posts into zed posts when using a mansaver unless you drill a full-depth pilot hole first. A trick for remote farm and ranch fence is get some worn-out 1.5" S-cams from a truck shop's scrap pile and weld them onto the bottom of a pipe for a post, then drill your hole in solid rock at 1.5" and hammer the S-camshaft down in there until the pipe is flush.
